I really don't understand why producers create new and good characters and then kill them by "Ainz Ooal Gown" , they want us to like this charater because it's main character of anime, and beside him create some other good characters like "Gazef Stronoff " or "lizardmen" or the humans who for first time went to his castle,
and i really don't understand the philosophy behind this, maybe the producers watched Game of thrones before making the story and wanna kill so many good people :-/
